Subject: Mathematics (7) Title: What's the Difference? Subtracting Integers
Description: In Cooperative/Collaborative groups, this lesson will actively engage students to subtract positive and negative integers. An "Essential Question" will be used to activate background knowledge and set the purpose for understanding integers. Students will play board games, use the Internet to play interactive games, and watch videos about subtracting integers.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
Subject: Mathematics (7) Title: Are You INTERESTed?
Description: In this lesson, students will explore simple interest through the use of studying loans and savings accounts. The students will generate the formula I=P x r x t to calculate simple interest on loans. Students will become familiar with "positive" and "negative" effects interest has on reallife applications.

Subject: Mathematics (6  12) Title: My Peanut Butter is Better Than Yours!
Description: The students will engage in the process of statistical data comparing data using tables and scatterplots. The students will compare data using measures of center (mean and median) and measures of spread (range). This lesson can be done with the worksheet or adapted to let the students use a graphing calculator to create their own scatter plot from the data table. This lesson is modified and adapted from Samples and Populations, Connected Math, Prentice Hall Publisher.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Arts Education (7  12), or Mathematics (5  12), or Technology Education (9  12) Title: Just the facts! Exploring Order of Operations and Properties of Real Numbers
Description: Students use their imagination while learning the importance of 'Order of Operations' and 'Properties of Real Numbers'. This lesson incorporates class discussions, wiki and/or online discussion threads (free at www.wikispace.com and/or quicktopic.com), art and puzzles.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (7) Title: Battle to the Death: Adding Integers
Description: The goal of this lesson is for students to use manipulatives to add integers, creating concepts rather than memorizing rules. This lesson will be related to the 300 Spartans who battled the invading Persians at the Battle of Thermopylae, inspiring the hit movie "300" and Stephen Pressfield’s historical fiction, The Gates of Fire. Interdisciplinary connections will be made to literature, theater, and history, discussing why Pressfield called this the most important battle in establishing and securing democracy in western civilization. This lesson is a base for many subsequent lessons including subtracting integers, combining like terms when simplifying algebraic expressions, and solving algebraic equations.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (7  12) Title: Calendar Fun Operations
Description: This activity is designed to help students evaluate numerical expressions by using order of operations. The students will be provided a calendar for the current month of the year. Students will then be provided with a worksheet that contains 30 expressions and a different symbol for each expression. The students will manually calculate each expression using order of operations. Once the numerical value has been discovered for each expression, the symbol next to the expression will be drawn on the calendar for that date. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (5  7) Title: Integers Are Rising and Falling Everywhere! Adding and Subtracting Integers
Description: Students will expand from the idea of not only identifying signed numbers but to use them for numerical operations.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (7), or Social Studies (7), or Technology Education (6  8) Title: New York with $1200
Description: CONGRATULATIONS!!! You are Demopolis Middle School’s first –place winner of the annual MATHATHON!!!!!!!!!! You and three of your classmates have been awarded an exciting trip to NEW YORK CITY! You will each be given $1200 to cover all your expenses during your three day stay. You must use only your $1200 prize to cover all expenses (transportation costs, hotel accommodations, food, gratuities (tips), souvenirs, and entertainment). Please budget your money carefully – decide which purchases are most important and budget these first. Don’t forget to have fun!!
Subject: Mathematics (7), or Technology Education (6  8) Title: Modeling and Adding Integers Using Numbers Lines and Counters
Description: The purpose of this lesson is to enable students to add integers and apply this lesson to real life situations. In this lesson students will model and add integers using number lines and counters through the use of technologybased resources. Handson activities and class discussions will enhance and reinforce the objectives.
Subject: Mathematics (6  7), or Technology Education (6  8) Title: How Much Money Can I Make?
Description: This lesson is a technologybased activity in which students will research two careers they are possibly interested in pursuing. They will convert the average yearly salary of each career into an hourly wage and record their findings in a spreadsheet. They will calculate their weekly gross and net pay for each career choice.
Subject: Mathematics (7), or Technology Education (6  8) Title: Investigating Integers
Description: Students will create a multimedia presentation to demonstrate their understanding of integers. Within this presentation they will include information on how to compare and order integers and how to add and subtract integers by writing about situations where they may encounter integers. Additionally, they will create a word problem with a solution that reflects their understanding of adding or subtracting negative and positive integers.
